Indexed comments from everyone on every article within the site

Paul,
Unfortunately, that's not possible with JFBConnect. While Facebook has the widget for comments that can be easily added to articles, there's not an easy way to show an aggregation of all comments. It is something we have plans to implement, but it will take a bit of code and we'd need to create the looks from scratch, so it won't be done for quite a while.

We wish Facebook had an easy way to do this as well as it would help greatly with the social sharing and discovery aspects of the comments.. but I haven't heard of them working on it anywhere.

Hope that helps explain, even if it's not what you're looking for,
Alex
